I was busy working on the Amazon Web Services version of my Photo Sharing application (the App Engine version appeared in February 2008). I was able to create a domain with the name friseton.com. I then wrote a simple query against this domain:

select * from friseton.com where email=’[email protected]’

SimpleDB responded and told me that the select query had an invalid format. On a wild guess, I thought it might be the dot (.) in friseton.com. Sure enough, it was. I deleted the friseton.com domain, added friseton_com, and the query started working.

select * from friseton_com where email=’[email protected]’

I don’t know if there is any syntax around allowing the dot in the domain name, but I found this, it works, and I’m moving on with the demo. I’ll learn the ins and outs as I go.
